Specification of Letters Patent.

Patented June 3, 1919.

Application filed July 18, 1917. Serial No. 181,324.

To all whom it may concern Be it known that I, FERDINAND L. ScHoENINc, acitizen of the United States, residing at Brooklyn, in the county ofKings and State of New York, have inbent or broken, or in the event ofall of the wire being entirely unwound from the spool.

The primary object of the invention is to provide means which may beused with any of the machines of the above class, through which wire maybe fed, the said wire being normally out of contact with said means,until it is damaged or fed entirely through the spool, when the wirewill be thrown out of alinement and be brought into contact, causing thecompletion of the electric circuit and the sounding of the alarm.

With the above and other objects in view, the invention consists of "thefollowing novel combination and arrangement of parts, hereinafter morefully described and illustrated in the accompanying drawings, in whichFigure 1 is a diagrammatic view of a portion of a gathering and coveringmachine, showing the direction of feed of the stitching wire andillustrating the position of the alarm mechanism.

Fig. 2 is a detailed perspective view of the supporting frame.

Fig. 3 is a side elevation of the same partly broken away, showing themanner of housing the wire connections between the contact plates.

Fig. 4 is a cross-sectional view on the line- 44 of Fig. 3.

Fig. 5 is a detailed perspective View of one of the contact plates.

Fig. 6 is a similar view of the other plate.

Referring to the drawings in detail, like characters of reference denotecorresponding parts throughout the several views.

In illustrating the invention, there is shown a fragmentary portion of agathering and covering machine of the usual type and while the inventionis shown and described as applied to this machine it is of courseunderstood that it is equally applicable to any machine in which wire isfed and guided therethrough for anypurpose.

The invention includes. an attaching frame 10, secured to the member 11of the gathering and covering machine, by means of screws 12 which passthrough openings 13 provided in the frame 10.

The frame 10 is substantially U-shaped as illustrated and is providedwith oppositely extending arms 14 and 15, the arm 14 having located atits extremity the contact plate 16. The plate 16 is secured to the arm14 by means of screws 17 and is provided at one end with a right, angledterminal portion 18, which is adapted to contact with the extremity ofthe arm 14 and to carry thereon a binding post 19. The opposite end ofthe plate 16 is formed with a laterally extending lug 20, which isprovided with a threaded opening for the reception of a set screw 21, toprovide means for connecting a wire 22 to the plate 16. The wire 22 ispreferably insulated and is threaded through a passage 23 formed in theframe 10, which frame is composed of fiber or other insulating material.

The opposite end of the wire 22 is connected by means of one of thescrews 24, to a contact plate 25, which is preferably secured to theinner end of the arm 15.

The plates 16 and 25 are provided with openings 26 and 27 respectively,for the passage of the stitching wires 28 and 29 of the machine, whichwires are fed through the machine and held in alinement by means ofspring guides 30 and tubular guiding mem bers 31, the openings 26 and 27being located directly in front of and in alinement with the entrance ofthe tubular guides 31. One lead of an electric circuit 32 is connectedto the binding post 19 and included in this circuit is an alarm 33, aswitch 34, and a source of electric energy 35, the opposite lead of thecircuit being connected to the frame of the machine as shown at 36, sothat an open circuit is provided that includes both contact plates 16and 25.

The wires 28 and 29 feeding through the machine are held in theiralinedposition and out of contact with the openings 26 and 27 throughwhich they pass, but should either of the wires become completelybroken, or for any other reason become disalined, the said wire wouldengage its particular plate and complete the circuit and sound thealarm. For example, the wire 28 may contact with the plate 16 and thecircuit would be established through the binding post 19, the bell andbatteries, the connection 36 and through the Wire 28 to the plate16 Inthe event of disalinement of the wire 29, a circuit WOLllddR establishedfrom the battery through the conductor 32 and the bell 33, the plate 16,the conductor 22, the: plate 25, the wire-29, the conductor 37 and backto the battery;

It is believed that fromthe foregoing description when taken inconnection with the accompanying drawings, the construction, operationand advantages of the invention will=be-apparent. The right is reservedto make such changes in the form and propor- Gopiesof thispatent may-beobtained for five cents each, byaddres sing' the CommissionerofPatents;-.

tion of'the invention as will fall within the scope of the appendedclaim.

Having described the invention, what is claimed is:

The combination with a wire stitching machine of a stationary contactplate included in a normally open electric circuit,

the latterto contact with said plate to com-' plete the circuit andsound the alarm;

In testimony whereof I affix mysignature.

FERDINAND L. SGHOENING."
